if your in the southern hemi, which way does a compass point?

To keep things simple, I left out the part from the link of it moving ~10 miles per year.

Weren't the magnetic poles suppose to switch?

Hey, let dug777 go :|

At some point the poles are going to flip. So one day the world will wake up and North will become South!!

(learned this in my physics 3 class)

It would point to the large magnet I shoved up your rectum.

Nah, as long as his water bowl is filled with liquor, he'll be happy, even chained up. Trust me. 😉

it'll go haywire and spin around, making it useless. near the poles, you need a gyrocompass (or GPS, if that's more to your liking)

(Assuming you are at Magnetic North)
I don't think so - why would it spin around? The magnetic field isn't randomly fluctuating. It would however, be quite sensitive to small distances when approaching the pole. It'll try to line up with the field, which would be straight down, although this may be impeded by the spindle.

(If you are at true north, it'll point at magnetic north)

Anyway, GPS is nearly useless near the poles - essentially above the arctic circle. The satellites are in highly inclined orbits, and never cover high lattitudes. The European Galileo satellite navigation system will address this (more densely populated cities at high lattitude) by using less inclined orbits and more satellites.
